A new generation of active harmonic filters unveiled

Schaffner, a specialist in the fields of electromagnetic compatibility and power quality, announces the introduction of the eco sine active sync, a new generation of active harmonic filters.

Drawing on the company’s broad knowledge and experience of applications and solutions in power quality the new modular ecosine active sync series offers best-fit technical and cost effective solutions for the most demanding harmonic mitigation tasks and is suitable for use with any kind of non-linear load.

Alex Kamenka, Head of PQ Business Unit, Schaffner comments, ” Our new ecosine active sync harmonic filters offer excellent performance in solving power quality problems, achieving <5% THID even on complex mixed loads and changing load profiles. This range adds to the very comprehensive portfolio of PQ products from Schaffner, meeting the demanding requirements of our customers and their applications in a format which is easy to install and maintain”.

The ecosine active sync filter series provides a complete solution concept which is modular and smaller than conventional filters and can be used as stand-alone modules or as part of a complete system solution. Typical applications include, building technology, automation industry, data and banking centres, elevators, cement industry, HVAC installations, battery charges, oil and gas exploration, paper mills, ship propulsion, steel industry, tunnel ventilation, UPS systems, water/wastewater treatment, welding equipment, wind turbines, machines and automation.

The new modular design with intelligent system approach offers tailored solutions for different applications and customers and employs 3-Level IGBT inverter topology for reduced power losses and a 3 DI programmable Digital I/O.

Key features include, highly effective harmonic mitigation up to the 50th order, parameter setting for even and odd harmonics, extended temperature range of modules up to +50°C, over temperature, over voltage and under voltage protection, ultra-fast and dynamic reactive power compensation (inductive and capacitive), load balancing and unloading of neutral wires, flicker compensation (if caused by reactive power), compliance with IEEE 519, EN 61000-3-12 and other power quality standards, system input 3-phase 3-wire or 3-phase 4-wire, user-friendly, compact, easy to install and maintain.
